Blazor InputSelect with multiple enabled throws NullRefException if nothing is selected

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

If there is an InputSelect in an EditForm with multiple values (via array) and nothing is selected (or everything is deselected) the following exception is thrown:
```plain
System.NullReferenceException: Object reference not set to an instance of an object.

at Microsoft.AspNetCore.Components.BindConverter.FormatterDelegateCache.<>c__DisplayClass3_0`1.g__FormatArrayValue|0(T[] value, CultureInfo culture)

at Microsoft.AspNetCore.Components.Forms.InputSelect`1.BuildRenderTree(RenderTreeBuilder builder)

at Microsoft.AspNetCore.Components.Rendering.ComponentState.RenderIntoBatch(RenderBatchBuilder batchBuilder, RenderFragment renderFragment, Exception& renderFragmentException)
```

Assuming the following model
```csharp
{
public List<(bool, string)> CurrentRoles { get; set; } = new List<(bool, string)>();
public string[] SelectedRoles { get; set; } = [];
}
```
And the following markup:
```csharp

No such exception

Workaround is to set the array to [] in ``OnInitializedAsync``

### Steps To Reproduce

1. checkout https://github.com/Tornhoof/InputMultiSelectRepro
2. make sure line 76 (Model.SelectedRoles ??= []) in Home.razor is commented
3. Start project
4. Deselect FirstRole in the Input Select Field

### Exceptions (if any)
```plain
